2 Claims.

The present invention relates to new and useful improvements in meansfor fastening the corners of various structural elements, such ascrates, boxes and various types of furniture having side members adaptedfor attaching in a position at right angles to each other, as well asembodying a construction adapted for securing panels in edge to edgerelation.

An important object of the present invention is to provide a fasteningattachment of this character of simple and practical construction, whichis strong and durable, relatively inexpensive to manufacture andotherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the de tails of construction andoperation as more fully hereinafter described and claimed, referencebeing had in the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which- Figure 1 is. afragmentary group perspective view of a corner fastener embodying myinvention.

Figure 2 is a fragmentary side elevational view showing the fastener. inassembled position.

Figure 3 is a group plan view of the meeting edges of two side membersof a structure to be fastened together and showing the holding platesecured thereto.

Figure 4 is a sectional view taken substantially on a line 4-4 of Figure2.

Figure 5 is a sectional view showing a modified fastening attachment forthe holding plate.

Figure 6 is a fragmentary sectional view of the modified fastener deviceshown in Figure 5.

Figure '7 is a fragmentary bottom plan view of a panel fastening deviceembodying my invention.

Figure 8 is an edge elevational view thereof.

Figure 9 is a sectional view taken substantially on a line 9-9 of Figure7.

Figure 10 is a perspective View of one Of the double locking platemembers for the panel fastener.

Referring now to the drawings in detail and with particular reference tothe form of the invention illustrated in Figures 1 to 4, inclusive, thenumerals 5-5 represent a pair of side members of a box, crate or thelike adapted for connection in a position at right angles to each other,the inner surface of the members having cleats 6-6 cemented or otherwisefixedly secured thereto and provided with downwardly inclined edges 1.

Secured to the outer surface of the cleats 6 are the holding plates 8-8,the side edges of the holding plates also being inclined as shown at 9and projecting outwardly beyond the inclined edge I of the cleats 6 soas to form flanges Ill-I0 which are spaced from the adjacent surface ofthe members 5-5. A pair of locking plates I l-l l of substantiallytriangular form have one edge secured to the underside of atriangular-shaped push plate I 2 by means of hinges l3-l3, the lockingplates ll being adapted for engagement behind the flanges Ill-Ill of theholding plates for securing the members 5-5 in assembled position.

A threaded metal plate I4 is secured to each of the lockin plates II inalignment with an opening l5 in the associated member 5 for receiving afastening screw I6 to secure the locking plates ll against accidentaldisplacement.

The locking plates I l have inclined edges l'l-l I cooperating with theinclined edges 1 of thc cleats 6 to provide a wedgingv fit for thelocking plates to draw the adjacent ends of the members 5 closelyagainst each other in a, manner as will be apparent.

In the form of the invention illustrated in Figures 5 and 6 of thedrawings the holding plates are designated at [8 and the locking platesl9 connected to the push plate b the hinges 2|. In this form of theinvention the edge of the locking plate I9 is formed with a verticallyxtending slot 22 adapted to receive a bolt 23 carried by the side member24, the bolt being provided with a wing nut 25 for securing the lockingplates in position.

Figures 7 to 10, inclusive, illustrate the invention adapted for use inconnecting a pair of panel 26-26 in edge to edge relation, the panels,at their meeting edges being formed with holding plates 21-21 includingthe flanges 28-28 behind which the triangular-shaped locking plates29-29 are positioned. The locking plates 29-29 are formed on one edge ofa bar 30 which is positioned in bridging relation with respect to the.meeting edges of the panels as will be apparent from an inspection ofFigure '7 of the drawings.

One edge of the bar 30, adjacent each end thereof, is beveled as shownat 3| adapted for conformably engaging the bevel edges 32 of cleats 33secured to the opposite side of the panel in any suitable manner, suchas by screws or bolts 34.

A pair of the bars 30 with the locking plates 29 are positioned adjacenteach side edge of the panels 26 and one of the bars 36 is provided witha locking bar 35 pivoted to the bar 36 as at 36 with the free end of thelocking bar adapted to enter a notch 31 formed in the other of said barsand eomprising'aw-holding plate .secured to each element andincludingsa' flange on each plate spaced from its associated element andcooperating with its associated element to form a chan nel on thesurface of the element, and a pair of locking plates adapted forpositioning flatly against the respective elements with one edgeslidably inserted in said channels, a connector P and means swingablyconnecting thelocking plates at right angles to each other to theconnector plate for insertion of the locking plates as a unit behind therespective flanges.

2. A corner fastener for a pair of right angularly disposed members,said fastener comprising a holding plate secured to each member adjacentthe corner and including a, flange spaced from the member, a pair oflocking plates adapted for insertion behind the respective flanges, aconnector plate, ,andhinges connecting one edge of each of'thelockingplates to' one sideof the connector plate with the locking platespositioned atright angles to each other for moving the latter as a unitinto and out of locking position, said locking'plates being foldableagainst the connector plate when not in use.
